morgan stream switcher

i'm using the latest version of morgan stream switcher (0.97) with the latest version of bsplayer (0.86 Build 493) and, well, i suppose i'm not using it with bsplayer, because it's not working at all. any clues here? it just WON'T work at all. i've got a slew of files that use dual audio streams, and i do love BSplayer, but i just can't use these files with this player at all. any pointers?

thanks!
